The Fermi GBM team reports the detection of a likely SHORT GRB
At 13:29:20 UT on 30 Jan 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260130A (trigger 791472565.82111 / 260130562).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 48.7, Dec = 64.2 (J2000 degrees, equivalent to J2000 03h 14m, 64d 12'), with a statistical uncertainty of 1.6 degrees.
The angle from the Fermi LAT boresight is 16.0 degrees.
